Tektronix 533A Oscilloscope
Type 533 533A
/Oscilloscopes are general
purpose instruments well suited to laboratory use. Plug-In
preamplifiers are used in the vertical-deflection system,
permitting the instruments to be used in many specialized
applications, including, among others, wide band, dual
trace, low level, differential, maximum frequency response
and risetime, and transistor risetime checking.
Specifications listed below apply to both the Type 533 and
except in cases that are otherwise noted.
Vertical Deflection System
All specifications for the Vertical Deflection System of the
Type 533 and 533A
Oscilloscopes depend upon the Plug-In
used with the instrument. The following specifications are
given assuming that a Type K Plug-In
unit is used.
Bandpass — DC to 15 me (down 3 dB :±y2 dB at 15 me).
Risetime — .024 microseconds.
Delay Line — Balanced network Signal Delay-—0.2 /¿sec.
Horizontal Deflection System
Triggering Modes—Type 533, Automatic, AC Fast, AC Slow, DC
and High Frequency Sync. Type 533A
Automatic, AC Low
Frequency Reject, AC, DC and High Frequency Sync.
Triggering Signal Requirements
Internal—a signal producing 2 mm of vertical deflection
except 4 mm in automatic and DC modes. External—a signal of
.2 volts to 10 volts, peak to peak. (The sweep will trigger
on larger signals, but the TRIGGERING LEVEL control operates
over a ± 10 volt range.) Automatic mode requires 0.4 V.
Triggering Frequency Range—-triggered operation to 5 me.
Synchronizing Signal Requirements
Internal—-a signal producing 2cm of vertical deflection.
External—a signal of 2 volts.
Synchronizing Frequency Range — synchronized operation 5 me
to 30 me.
Twenty-four position switch provides calibrated sweep rates
from .1 /¿sec/cm to 5 sec/cm. Accuracy typically within 1%
of full scale; in all cases within 3% of full scale.
Continuously variable sweep rates are available from .1
/¿sec/cm to 12 sec/.cm
Six degrees of sweep magnification are provided; 2, 5, 10,
20, 50 and 100 times. Accuracy within 5% when the magnified
sweep does not exceed the maximum calibrated rate of 0.02
